Receiving part with optimal axial play for a moving part of a switch

摘要

The cam arrangement (1) has a pin (3) sliding longitudinally in a hollow modified triangular-section housing (2). A spring (8) surrounding the pin pushes its rounded end (4) against a contoured cam surface (4b). A thickened part of the pin (5) forms a shoulder against which the spring may push. The thickened part of the pin slides in the end (6) of the modified triangular-section housing. The narrow end of the pin slides in a round hole in the flat end wall (7) of the housing. The spring presses on the inside surface (7a) of the flat end wall.
